RADIATOR-ASSEMBLING MACHINE.

Specification of Letters Patent.

Patented Mar. 12, 1912.

Application filed August 2, 1907. Serial No. 386,757.

To all whom it may concern:

Be it known that I, WILLIAM C. Mo- Known, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Radiator-Assembling Machines, of which the following is a specification.

.My invention relates to an improved radiator assembling-machine for connecting sectional radiators.

The primary object of my invention is, the production of an assembling-machine whereby the several sections of a sectional radiator may be quickly and conveniently assembled and connected with assurance that the sections will be properly alined, and connected in a water-tight manner.

Other objects are, to provide an assembling-machine whereby the sections are drawn together into connected condition, in contradistinction to the old method of pushing them together which is liable to cause them to become disalined; to provide a rotatable support for the radiator sections so that when they are assembled and connected they may be carefully examined at every point without removing them from the machine; to combine with the assemblingmechanism, means for testing the radiator under pressure; and to provide for quickly and conveniently adjusting the machine to re ceive and-effectively assemble and connect any number of sections.

Further objects are to make the support for the sections adjustable so that sections of any height may be assembled and connected; to control the power-mechanism from any point in the length of the machine; to provide a rigid head that acts as an abutment for one end section and has air and water communication with the interior of the assembled and connected sections; to provide a follower which is drawn toward the abutment by a power-device in rear of said abutment; and to otherwise improve on machines for this purpose heretofore in use.

My invention consists in the combination and arrangement of devices, and in the construction, arrangement and combination of parts to be hereinafter described and particularly pointed out in the appended claims.

In the drawings,-Figure 1 is a side elevation of an assembling-machine embodying my invention in a representative way; a plurality of radiator sections being shown supported thereon. Fig. 2 is a plan view of the same with the radiator sections removed. Fig. 3 is an enlarged horizontal section taken on line s-s, Fig. 1; the several radiator sections being assembled and connected. Fig. 4 is an enlarged transverse section taken on line t-t, Fig. 1; looking toward the left. Fig. 5 is an enlarged trans verse section on line t--t, Fig. 1., looking toward the right and showing the radiatorsupport turned to incline the radiator supported thereon. Fig. 6 is a section similar to Fig. 5 with the radiator-support in normal position and the radiator removed. Fig. 7 is an enlarged transverse section through the power-cylinder on line r-?), Fig. 1. Figs. 8 and 9 are transverse sections taken on line te-10, Fig. 1; looking in opposite directions. Fig. 10 is an enlarged vertical longitudinal section taken on line w-m, Fig. 9. Fig. 11 is a central longitudinal section of the controlling-valve. Fig. 12 is a section taken on line v 1 Fig. 11. Fig. 13 is a section taken on line zs, Fig. 11. Fig. 14: is a section similar to Fig. 3, showing a waterradiator and the manner of assembling and connecting the same.

Referring now to the drawings in detail, like numerals of reference refer to like parts in the several figures.

The reference numeral 14 designates a pair of standards at one end of the machine, each of which has a box 15 at its upper end in which a guide-rod 16 is fixedly secured and acts to guide one end of a supportlng-frame 17 on which the several sec tions of a radiator are to be laid preparatory to connecting the same.

Two standards 18 are located at the opposite end of the machine, and between these a power cylinder 19 is located; the latter has a stuiling-box 20 on one of its heads which is held in a box 21 at the upper end of one of said standards and a boss 22 on its other head which is held in a box 23 at the upper end of the other of said standards. In this manner the cylinder is rigidly secured and it has its axis coincident with that of the guide-rod 16 at the opposite end of the machine. lVithin the cylinder is a reciprocating piston of ordinary construction to which is secured a piston-rod 2 1 that passes through the stuffing box 20 of the cylinder and has its outer extremity affixed to a head 25 in a manner to permit the latter to rotate thereon but to compel said head to reciprocate with said rod.

A head 26 is slidable on guide-rod 16 and it is connected with head 25 by four parallel bars 27; said heads and bars constituting the supporting-frame 17 which reciprocates with the piston and is rotatable independent of the latter.

An abutment 28 is fixedly secured to the inner standard 18 and it has four segmental slots 29 equipped with bushings 30 which are adjustable in said slots and through which the supporting-bars 27 are passed. Heads 25 and 26 have similar segmental slots 31 which are provided with bushings 32 adjustable within said slots.

The several sections of the radiator are laid upon the two lower bars 27 which are in a plane beneath the axis of the abutment so that the longitudinal center of the radiator is approximately coincident with said axis. One end section of the radiator to be assembled and connected is first laid upon the two lower bars and placed against said abutment and the remaining sections are then laid upon said bars with tapering nipplesentering the alined openings of said sections. After the several sections consti tuting the radiator are assembled, an ad justable follower 38 is moved against the other end section. Said follower has a header 39 adjustably secured thereto which has laterally adjustable bearing-blocks 39 that bear against said last mentioned end section, and said follower also has segmental" slots 40 in which bushings 41 are adjustably held through which the bars 27 arepassed. Each of said bushings in said heads 25 and 26 and follower 38 and the bushings in the abutment 28 comprise a cylindrical body or sleeve 42 which has a flange 43 at one end that bears against one side of the follower, head, or abutment, and at its other end it is exteriorly threaded to receive a nut 44 that bears against the other side of said follower, head, or abutment, as the case may be. Upon slightly unscrewing said bushings, they may be adjusted to any position in the segmental slots; thereby bringing the bars 27 closer together or separating them more, as may be necessary for the different heights of radiator sections. Each of the bushings of the follower also has an extension 45 through which a headed pin 46 is passed whose lower end is secured to a pawl 47 pivoted to the bushing, at 48, and having its free in engagement with one of a series of notches 49, on each of the rods 27. Around said pin, between said extension and the pawl is a coil-spring 50 which serves to hold the pawl in engagement with the proper notch in the corresponding bar. Each of the notches 49 has one of its walls at a right-angle to the directions of move ment of the follower and its other wall inclined; thereby permitting adjustment of the follower toward the abutment by pressure in that direction. It is apparent therefore that the follower can be quickly adjusted to any length of radiator.

51 designates a supply-pipe for the power-medium, which may be air, steam, water, or any other agency to cause the piston to reciprocate within the cylinder; but I have arranged the machine herein illustrated, for use of water as the power-agent. The supply-pipe 51 is connected by branchpipes 52, 52*, with two inlet ports 53, 53 of a valve-casing 54 having a rotatable valve 55 therein; and from ports 56, 56*, in said casing, pipes 57, 5'7 are led. to opposite ends of the power-cylinder. Outlet ports 58, 58 are provided in the valve-casing into which discharge pipes 59, 59 are threaded that lead to the sewer or any other suitable point. It is to be noted that the inlet ports are on opposite sides of the valve-casing, and opposite each inlet-port an outlet-port is located.

The valve has two L-shaped passages 60,-

60, and one or the other of the ends of said passages are always in registration with the ports 56, 56*. As shown in Figs. 12 and 13, the water under pressure enters port 53*, passes through the L-shaped passage 60 out the port 56 and through pipe 57 into one end of the power-cylinder, thereby forcing the piston toward the opposite end, causing the water in the last-mentioned end of the cylinder to pass through the pipe 57, into port 56, through -Lshaped passage 60, and out port 58 into discharge-pipe 59*. On turning the valve one-quarter of a revolution to the left, the action of the piston would be reversed and as the support 27 is connected with the piston and the follower 38 is carried on the support, the movement of the piston in one direction causes the several radiator sections to be drawn together, and during such action they are connected in a water-tight manner by nipples 61 that are tapered in opposite directions from a point midlength as shown in Fig. 3 and consequently act to securely tie the several sections of the radiator together. Movement of the piston in an opposite direction causes the follower to be moved away from the abutment and allows the completed radiator to be removed.

I consider the assembling and connecting of radiator-sections by a pulling action to be a very important feature of this invention, as it assures proper introduction of the connecting-nipples into the alined openings of the several sections and perfect alinement of the latter, and it almost entirely eliminates leaky joints between the sections. j

The abutment 28 is provided with a header 62 which is adjustable thereon and when the lower bars of the supportingframe are adjusted to a lower plane with a view of bringing them closer together for supporting radiator sections of less height, header 62 and the header 39 of the follower are lowered also to center them with the loagitudinal center of the radiator sections. Header (32 has transversely adjustable bearing blocks 63; and these blocks and the bearing-blocks 39 on the header of the follower are adapted to bear against the upper and lower ends of the end sections, preferably against bosses G4 and the circular flanges 65 around the openings in the end sections, as shown in Fig. 3; the blocks closing said opening being provided with leather or other suitable facing or packings 66 so that said openings are closed in a water-tight manner. One of the blocks of the header on the abutment has two passages therein, one an air-passage 67 and the other a water-passage 68, both in communication with the interior of the connected sections by reason of their opening into the opening of the adjacent end section. An air-supply pipe 69 is connected to passage 67 and has a valve 70 therein, and a water supply-pipe 71 is connected to passage 68 and has a valve 72 therein. A water discharge-pipe 73 is connected with the supply-pipe 71 and is led to the sewer or other convenient point for discharging the water from the radiator; it having a valve 7 1 at a point between its discharge end and its point of connection to the water supplypipe. One end section is provided with the usual threaded pet-cock opening 75 into which a pet-cock 76 is screwed. iVhen testing the machine, the valve 70 in the airsupply pipe and the valve 74. in the waterd1scharge-pipe are closed; the pet-cock 7G and the Valve 72 in the water supply-pipe are opened. lVater under pressure then enters the radiator and forces the air out of the pet-cock, which is closed as soon as water is discharged therefrom, whereby the radiator is subjected to the water pressure and may be examined at all points by re volving the supporting-frame. If upon examination it is found that the radiator is free of leaks, the valve 72 in the water supply-pipe is closed, and the valve 70 in the air supply-pipe and the valve 74 in the water discharge-pipe are opened; whereupon the air under pressure enters the radiator and forcibly ejects the water from the radiator through the discharge-pipe, carrying with it any fine particles of sand remaining from the core or any other loose matter therein.

In Fig. 14 I have shown my improved sembling machine in use for assembling and connecting a sectional water radiator. When so used, I employ a different bearingblock 77 on the header of the abutment; said block having a passage 78, and a pipe 7 9-threadcd into said passage and provided with a pet-cock S0 or analogous device.

\Vhen testing a water-radiator, the petcock S0 and the valve 72 in the water supplypipe is opened, the water under pressure entering the radiator and forcing the air therefrom through the open petcock. When water appears at the pet-cock, it is closed; the radiator is then carefully examined and if found tight the valve in the water supply-pipe is closed, and the valves in the filP-SHpPlY-PlPO and the water discharge pipe are opened, thus admitting air under pressure to eject the water from the radiator through said discharge-pipe. In this manner the assembled radiator may be conveniently tested under pressure without removing it from the machine, and in order that all parts of the radiator may be carefully scrutinized while testing the same,

the supporting-frame may be turned as shown in Fig. 5.

In order that the controlling-valve 55 may be operated from any point along the length of the machine, a lever 81 is secured thereto which has attached to its outer end a rod 82 that extends the full length of the machine and is slidably supported in a support 83 secured to the head 26 or in any other manner.

NVhile the construction shown and described herein is the preferred one, it is to be understood, that variations and changes may he made therein without departing from my invention or sacrificing any of the advantages thereof.
